After reviewing the latest engine data logs, the recommendation from the engine & fuel system folks is that I swap the injection lines between #2 and #4, so that the output port on the fuel spider feeds a different cylinder. Then see if the EGT drop stays with the cylinder, or follows the port. So, went out to the airport tonight to make that swap. The nozzle lines are barely long enough to do it, but with careful bending and securing with Adel clamps, I moved the injector ends of lines 2 & 4 to the opposite cylinder. Finished up far past dark, so obviously no test flight tonight…will have to wait for the weekend.
